Member Function Documentation

void fei::Matrix_core::copyTransposeToWorkArrays ( int  numRows,
int  numCols,
const double *const *  values,
std::vector< double > &  work_1D,
std::vector< const double * > &  work_2D 
) [static]

Given a 2-D table (C-style list-of-pointers) of size numRows X numCols, copy the transpose of the data into the given 1-D work array and set the given 2-D array of pointers to point into the 1-D data. In other words, columns in the input will be rows in the output, and the entries in work_2D will point to the beginnings of those rows (former columns).

Parameters:
numRows First dimension of 'values'. i.e., number of pointers in the list of pointers.
numCols Second dimension of 'values'. i.e., the length of each of the rows (all rows have the same length).
values 2-D C-style table of data. List of pointers of length numRows, with each pointer pointing to 'numCols' items.
work_1D on exit, will have length numRows X numCols, and will contain the data from values. The data from 'values' will be transposed such that the entries from each column of 'values' will now lie contiguously.
work_2D on exit, will have length numCols, and will represent a C-style list-of-pointers where work_2D[i] = &(work_1D[i*numRows]). In other words, each entry of work_2D points to a row which was a column of 'values'. work_2D represents a table with 'numCols' rows, each of length 'numRows'.

void fei::Matrix_core::setRHS ( fei::SharedPtr< fei::Vector rhsvector  ) 

If slave-constraints have been registered with the matrix-graph, and if the constraints have a non-zero right-hand-side coefficient, then this matrix needs access to the linear-system's right-hand-side vector for assembling data into. For more details, see the SAND report that documents the FEI's constraint reduction.

void fei::Matrix_core::setSlaveInfo ( fei::SharedPtr< fei::MatrixGraph matrixGraph  ) 

Instruct the Matrix_core to set its slave-constraint information (such as dependency matrix and constraint-right-hand-side vector) from the specified matrix-graph object.

int fei::Matrix_core::copyPointRowsToBlockRow ( int  numPtRows,
int  numPtCols,
const double *const *  ptValues,
int  numBlkCols,
const int *  blkColDims,
double **  blkValues 
) [protected]

Copy a rectangular (non-ragged) table of coefficients representing a set of point-entry matrix rows into a block-entry matrix row which is laid out as follows: blkValues[i], i in [0 .. numBlkCols-1], is an array containing the values for a single block-entry. The dimensions of the block-entry are numPtRows X blkColDims[i], and the block-entry values will be arranged in column-major order, meaning that each column of the block-entry occupies contiguous memory.
